Engine catalyst aging system and method for aging catalyst

An engine catalyst aging system which uses an engine as a programmable gas generator for aging a catalyst, the engine being fitted with standard engine injectors, an engine control module, an exhaust system, at least one exhaust gas oxygen sensor for providing exhaust gas oxygen signals to at least one exhaust gas signal input of the engine control module, and a wiring harness having multiple wires which terminate in a harness connector which inserts into an engine control module connector, the harness connecting the engine control module to the engine so as to include all related sensors such as the injectors and the exhaust gas oxygen sensor, the system comprising:

• means for generating at least one set of operator defined injector pulse widths for providing an operator defined fuel supply to the engine;
• means for switching the engine injection mode between the engine control module injector signals and said engine catalyst aging system;
• means for providing reference injector pulses from the engine control module;
• means for generating at least one set of simulated exhaust gas oxygen signals for the engine control module;
• means for switching at least one exhaust gas signal input of the engine control module between the at least one set of exhaust gas oxygen signals and said at least one set of simulated exhaust gas oxygen signals;
• and
• means for selectively breaking the wires of the harness providing an system/engine interface.
